Questions on HFM POV defaults in financial reports

Hello -

Let me apologize in advance for posting such elementary questions, but I am a new HFM administrator early on in my training. 

I have 2 questions on how to change the defaults on the POV menu's when running financial reports in workspace.

#1 - How do you change the rows per page default on the POV when running a financial report? The current default is 20 rows per page.  We would like to change the default to a max of 500 to always load for the users. 

#2 - Is there a way to have all the parent dimensions to open expanded and not collapsed also when in a POV in a financial report so you don't have to expanded each parent?
